Testing the efficiency of low power fuel cells

Napravljen je teorijski uvod u gorivne ćelije. Opisan je princip rada gorivnih ćelija, te elektrolizatora. Nakon uvodnog dijela pristupilo se pokusima upoznavanja s opremom. Proveden je pokus ispitivanja rada elektrolizatora, te dokazivanja kemijskog sastava vode. Odrađeni su pokusi ispitivanja proizvodnje i potrošnje vodika, te određivanja stope propuštanja spremnika vodika. Snimljene su karakteristike gorivnih ćelija u serijskom i paralelnom spoju. Pri testiranju su uočeni nedostatci u radu gorivnih ćelija, te je u objašnjen način na koji su oni otklonjeni. Ispitana je učinkovitosti pojedinih spojeva gorivnih ćelija, te učinkovitosti sustava gorivnih ćelija i elektrolizatora. Uspoređena je učinkovitost i radna snaga za različite vrste spoja ćelija. Odrađeni su pokusi ispitivanja radne točke sustava gorivnih ćelija i trošila.A theoretical introduction to fuel cells was made. The work principles of fuel cells and electrolyzer were explained. After the theoretical part, introductory experiments were performed to get acquainted with the equipment. An experiment was performed to test the operation of the electrolyzer and to prove the chemical composition of water. Experiments were made to test hydrogen production and consumption and to determine the leakage rate from hydrogen tanks. A fuel cell characteristics test was performed. During the experiments, defects were encountered. Elimination of defects was explained. Efficiency of fuel cell compounds and efficiency of fuel cell and electrolyzer system were tested. A comparison of efficiency was made depending on the type of fuell cell compound. Experiments were performed to test the operating point of the fuel cell and consumer system
